Personally, if I’m at a gig, some level of interaction between performer and audience makes such a difference. But if the on-stage antics/aesthetics are taking over the quality of the playing, then I would much prefer that the pay attention to what they are playing. I think it can also depends on the music. For example Joe Satriani is great at looking at the crowd and creates a great vibe - he has such a command over his playing. However, many moons ago I saw Tool live where they spent pretty much the while gig stationary position, making no real show of it - it was one of the best performances I have been to! The lack of visuals and the stellar sonic production had me almost hypnotized! Immersed completely in the music.
